Whether it’s geothermal technology, inverter compressors, or Internet of Things (IoT)-enabled devices, HVACR contractors are constantly on the lookout for the next big thing. When creating a definitive list of budding HVACR technologies in 2018, variable refrigerant flow (VRF) consistently ranks near the top.
While VRF is a primary heating and cooling choice in Europe, Japan, and China, where many buildings lack ductwork, it’s a relatively new option in the U.S., where ducted systems using direct expansion and chilled water equipment have been the preferred option.
